由于Eclipse一些问题，我失误把一个小maven项目删掉了，然后我从SVN上把以前的项目update下来，把自己备份的一些接口再粘贴到项目的目录下面，在对每一个接口进行单元测试时，出现
WARN o.a.cxf.phase.PhaseInterceptorChain - Interceptor for {http://webservice.internetfinance.com/}ICreditInfoWebserviceService#{http://webservice.internetfinance.com/}queryServiceItemByCode has thrown exception, unwinding now
org.apache.cxf.interceptor.Fault: Could not send Message.
这种错误。maven都是配置好的，就是不能单元测试了，百度了一下解决方案，感觉还是不理解。这个maven项目是依赖Spring的，我只是刚刚接触，底层的一些还不太了解，希望各位大神给一个思路即可。下面是所有 的错误：

结贴：最终还是没有找到原因。不过换了种解决的方法。导入项目时选择的是maven项目，而不是java已有的工作空间。
